Right coronary artery
Right Coronary Artery
The Right Coronary Artery (RCA) is one of the two primary arteries that supply blood to the heart. It originates from the right aortic sinus, a part of the aorta, and travels through the coronary sulcus, between the atrium and the ventricle.
Anatomy[edit | edit source]
The RCA typically gives rise to two main branches: the posterior descending artery and the right marginal artery. These branches supply blood to the right atrium, right ventricle, and the posterior two-thirds of the inter-ventricular septum.
Clinical significance[edit | edit source]
Blockage of the RCA, often due to coronary artery disease, can lead to a myocardial infarction (heart attack), specifically affecting the areas of the heart that the RCA supplies.
